Docker and R – Talk for the Greater Cleveland R Group

I was able to give a talk recently to the Greater Cleveland R Group about using Docker and R together. Docker is a virtualization platform that uses OS-level virtualization to provide containers. It’s pretty neat, so I wanted to share the talk here. Big thanks to Tim Hoolihan for both organizing the R User Group in Cleveland, and also filming and nicely editing my video when part of the presentation unexpectedly did not work.

Write your own! On having better habits as an R programmer

I contribute responses to Stack Overflow pretty frequently. I like answering well-written questions and enjoy that it keeps my skills sharp. However, one area of annoyance for me on Stack Overflow is that many answers start with something like: “You can do this using the <package name> package” - even when the task at hand can be handled in base R. For many posters, that’s probably not a big deal, but I find myself getting those answers occasionally on my questions, even when I explicitly ask for base R solutions.
